When fault pass enable, if the device has local alarm (errors on fiber Rx interface) the DCD signal of
V.35 interface will close and DTE device should have some denotation.
When fault pass enable, if the device has remote alarm (errors on fiber Tx interface) the CTS signal of
V.35 interface will close and DTE device should have some denotation.
After power on the DSR signal of this series device will be forever valid.

This bit is setup for forced monitor and management by the remote optical multiplexer
When optical multiplexers are working in pairs, if the module is plugged into RC001-1 single slot
chassis deployed at customer premise, the module will be automatically set up to be managed
by the host-site multiplexer; if it is plugged into RC002-16 16-slot chassis, to be managed by the
remote multiplexer, the module need to be manually set up to that working mode.
Relationship between DIP-switch and software configuration
The corresponding relationship of above device DIP-switch and network management ability is shown

Typical Application
The connection topologies introduced in this part is only for user reference. Users are advised to
design and deploy the most appropriate topology according to their specific environment.
Point-to-point, 'Master Clock – Slave Clock' Topology
When connecting Routers or other V.35 interface equipment point to point, routers should work in
DTE mode. For the convenience of installation and test, it is advised to set the local modem
'Master Clock Mode', and remote modem 'Slave Clock Mode'. That is, the timing resource is
from the local modem.
In "Master Clock-Slave Clock" topology, if DXC, MUX devices are in E1 link, the DXC, MUX and
remote modem should all be slave clock mode (follow the clock of E1 link)
Point-to-point, 'Terminal Clock – Slave Clock' Topology
When the remote DTE must follow the timing resource of local V.35 clock, that is to say the TX
CLOCK of local TX is inner clock source. In this condition, it is advised to set the local modem
'Terminal Clock Mode', and remote modem 'Slave Clock Mode'.
